esaoea TacZZwkmn-ti-may coneem: I Be it hown that I, RUDOLF'FROMMER, of IX. Kiilso Soroksari It 100, Budapest, Anstria-Hungary, factory manager, citizen of the Kingdom oi Hungary, residing at Budape'm, Austria-Hun ary, have invented certain new and use llmgrovements in and Relating toAutomatieirearms, of which the foilowing is a specification.

automatic firearms rovision is made thatupon theemp gli ng oI themagazine, that isft o after the of the last cartridge, the breech antoinaticfil opens so that the weapon is in condition or reloading. This result is attained because either the follower.

of the ma -azine or some part cooperating with said ollower, when the last cartridge has been fired and the magazine is empty, is

ence

with it, moves out of caused to engage wit the breech-bolt in order to hold the same in its rearward position: Whenrreloading takes place, by the downward movement of the said follower eitherthis latter or the part cooperating engagement with the breech-bolt and the closing of the breech takeslace automatically under the influoi the breech-bolt spring. Assuming that the Weapon is loaded means of a cartridge clip 1t is obvionsthat aftenthe cartridges have been slid into the magazine and the breech-bolt has been freed from the said engagement, the breech-b0lt to move forward blilit t e will have a "tenden' this movement wil be prevented by cartridge clip against which the breech bolt presses, so that the cartridge clip musfibe Y remoyedvbefore the Bree -hon; can move sure and to render' unnecessary a special forwarirland hus introduce a i e into the loadingfchamher; Wi li' this arrangeme t w e 'ythe pressure of the on the cartridge clip, especially in" the case'of small "arms, may be so considerable that it becomes exceedingly diflicult, or even uite impossible to withdraw the'cartridge" c ip; further, a special manipulation is necessary for the removal of the cartridge clip.

The present invention has for its object to relieve the-cartridge clip from this presmanipnlation such as has hitherto been reuired for the removal of the cartrid ith' this arrangement the means which serve to hold the breech-bolt afterthe mags zine has been emptied or" the last cartri Specification c'f gifietterfi Patent emanation filed Julie a, was. term so: acacia termined selected should preferably be additional handling or J avoided; and this is a further object of the present invention; The desired endmay be ge clip.

releasedtutomaticaliy as heretfofare by the l0adingo'r the depression of the follower, but is efiec'ted independently of the depression of the latter b means of apart operated by hand. If esir'ed, this part may be actuated by seizing the weapon at a predeplace, and in such a case the place 1 b & one which must necessari y e a e in a case when the weapon is renderefi ready for firing or is ready, as by this means any manipulation is attained with various construct-ions in different cases. By way of example the case may be'selected in Whichthe Inec 'anisin is arranged upon the small of the stock Where the marksman must necessarily seize the weapon on firing, so that he will simulta neously' actuate the device in accordance with this invention.

constructional form of this device is illustrated byway of example in the aOCOFfI- panying'drawings, in which:

showing the breech-bolt released, and Fig. 3 irepresents a section on the line A-B of Fig.1.

The breech-bolt 1 is retained in the guisigtion for loading by means of a pawl he cha'mfered face 11 of which engages in'a corresponding;chamfered recess 2 in the breech-bolt. The angle at which 'thereeess 2 andthe face 11 in engagement therewith are chainfered is such that the breech is able to "less forward the breech boltan depress t e pawl which latter is' jiidta'ted around the pin 4 against the pressure of a spring 3'. When the magazine is emptied or" the last cartridge has beenfiredg the ollow'er '6 ascendsto such a height that the nose 7 thereon rotates a catchS which is rotatabiy Inountednpon the pin 9', so that the nose 12 formed on this catch comes beneath the tooth 1t? of the pawl 5. B th s means depression of the pawl 5 is ren ere'd impossible-so that the breech-bolt 1 is locked in the open "ii'sig;

. .Y so I Figure-1 represents. a side View partlg H1 section, showing the breech-bolt bake in open position. Fig. 2 is a similar View,

25 depression of a stud 24 projectin pawl 5 upon the nose 12 passes thrqugh the pivot 9 so that the pawl 5 and the catch 8 constitute a ri id member.

Now when t e follower 6 is dfepressed by 5 the loading of the.magazine 1 1) the locking pawl 8 is in no way afiecte thereby, that is to say this awl remains in its position in which it hol s the breech-bolt 1 0 en; if therefore there is a cartridge clip in "out 10 of the head of thebreech-bolt this cartridge clip will also remain in its position in which 1 it is not influenced by the-breech-bolt 1, after the loading of the magazine, so that it may be readily removed by hand. By means of this arrangement, therefore, the cartridge clip is completely relieved from the pressure of the breech spring and consequently the arrangement of the cartridg clip WhlCh is usually employed in ban 0 erated .fire- 2o arms (and whlch'is supports in front of the head of the breech-bolt at two points only) may be utilized. The awl 8 which is brought into engagement with the awl 5 by the follower 6 may be released y the from the pawl 8, but in order that it may e possible to completely efiect the removal of the cartridge clip, upon which no ressure is now exerted, without any special manipulation, in the (Ease represented by way of example in the accompanying drawing the lever 13 is provided upon the small of the stock and is connected with the rod 15 moving in a slide wayand acted upon by the s ring 1.4:- This rod15 is provided upon its out extremity with a hook 18 rocking around the pin 16 and acted upon by the spring 17, this hook, as shown in Fig. 1 being normally situated in front of the nose 19 of the pawl 8. 40 If now on preparing to fire the small of the stock is seized whereby the lever 13 is pressed into the recess 20 in the stock, the hook 18 of the rod 15 will be moved back thereby engaging with the nose 19 of the pawl 8 and as the pawl 8 is rocked thereby around the pin 9 it will move out of the way of the tooth 10 into the recess 21 in the pawl 5, thus releasing the catch, whereupon the breechbolt 1 is free to move forward under the influence of the breech spring (Fig. 2) and at the same time detaches the cartrldge clip. When the lever 13 is released, the rod 15 will again be pressed forward by the springl i thus bringing the hook 18 into en agement with the nose 19 of the pawl 8. gwing to the chamfering of these two cooperating parts 18 and 19, the hook 18 will be depressed against the action of the spring 17 and will resume its original position in front of the nose 19; the device is therefore again in operative Position. The device described above may also be advantageously employed for automatically securin fire arms and for this purpose it is mere y necessary to provide the rod 15 in its retracted positlon,

esaooa with a stud or projection 22. lin the inoperative position of the lever 13 this stud 22 is in a position in which the trigger 23 would act upon it when firing takes lace,

so that firing is rendered impossible. en, however, the small of the stock is seized and the lever 13 consequently pressed into the same, the stud 22 is moved out of the ath of the trigger. Firing is therefore only possible when the weapon is in condition for firing, while in all other cases it is rendered impossible. The stud 22 may be provided upon the trigger 23 a recess being then formed in the rod-15 in a corresponding position so that when the stock is seized, it 30 comes in front of the stud on the trigger in such a manner that when firin takes place the stud is able to pass throug this recess.

Having now particularly described and ascertained the nature of my said invention 35 and in what manner the same is to be performed, ldeclare that what I claim is l. in automatic firearms the combination of a receiver provided at its to with a loading opening, a magazine, a fol ower-therein, a reech-bolt, means adapted to retain said breech-bolt 'in its retracted position, intermediate means arranged between said follower and said bolt-retaining means and adapted to lock said bolt-retaining means in its retaining position being itself actuated by the said follower when the magazine becomes exhausted, and means independent of the said follower for releasing the said breech-bolt.
